APPARATUS IEOR'WASHING AND SIZING.

Application led February 15, 1915.

To all whom it may concern Be it known that I, JOHN Gr. KIRRSEY, a

' citizen of the` llnited States, residing at Seattle, in the county of King 'and State of liVashington, have invented certain new and useful Improvements in Apparatus for lVashing and Sizing Such Material as May be Adapted to Separation into Different Sizes, of which the following is a specification, reference being had therein to the accompanying drawings. t

This invention relates to certain newand useful improvements in 'apparatus for sizing or classifying material., either in a dry or wet state, or with or without using water, as the material comes from coaly and placer mines or other adapted material, and giving as many different sizes as there would be screens employed in the construction. even down to a very fine mesh or size as might be desired. p

Another object of my invention is to provide an` apparatus, by means of which a far greater tonnage of `material can be sized in a given time than with other classes of sizing machines and at a greatly reduced cost per ton for sizing, with a minimum of horse power to operate same, with low cost of upkeep, and giving a plurality of sizes for separate and better treatment-as in ore mills andfor concrete work.

Another object of my invention is to provide an apparatus whereby the material, on

lthe highly inclined screen cloths is given a very rapid travel, due to the rapid cushioned jar or deadened percussion stroke given to the screen carrying frame, and which gives a rapidy bouncing downward movement to the material in passing over the screens, thus practically overcoming the scour, friction and wear of the screen cloths, thus giving longer life to the screen cloths, and also avoiding the clogging of the screen meshes.

Another object is to mount one above the other, a plurality of screens of different mesh, the coarsest being the topmost, or one firsty receiving the material, with each succeeding lower screen of liner mesh, and in such manner of construction that each upper screen will discharge the material passing therethrough onto the head or high end of the one next below, and so on through the series, so as to occupy or require but little floor space for such apparatus.

Specification of Letters Patent.

serial No. 8,339.

Another and further object of my invention is to provide a machine with a plurality of different sized mesh screens, thereby givmg larger tonnage capacity, with few or practically no moving or wear parts, and one with which the associated tine or comminuted material can be readily separated.

Other and further objects and advantages, presented in this improvement will be made manifest in considering the following details of construction, in connection with the accompanying drawings.

Figure l, is a perspective view of my improved device, as would bemounted for treatment of certain classes of material. Fig. 9., is a perspective view of the spring supported metal frame, with contained removable screen carrying pans or receptacles. Fig. 3, is a vertical side sectional view of same. Fig. 4, is a perspective view of the removable screen carrying pan, with parts broken away. Fig. 5, is a broken vertical side section, showing the stationary feed conveyingy pans or launders, leading to the uppermost screen of the operable inner metal frame.

Like numerals of reference refer to like parts in the several drawings.

Referring to the drawings l denotes the base members, 2 the uprights, 3 the intermediate side members and 4 the upper members comprising the main or heavy outer frame in which is mounted the inner metal or screen frame.

5 designates the superposed inclined hopper frame attached to the outer frame aforesaid and 6 the side frame members supporting the operating shaft for this apparatus hereinafter more particularly described.

7, is a platform shown-partly brokenupon which to stand to regulate the wash water and operate the hinged adjustable grizzly, when such is used.

8, are rods for more securely holding together the wooden frame.

Water supply pipes 9, provided with a plurality of controlling valves 10 are mounted upon the frame and held in position in any desired manner, as by means of clips 11, said supply pipes being provided with lateral apertured branches arranged in proper position with respect to the grizzly and screen members hereinafter described, being provided with closing caps l2, whereby the larger pieces of the material which fail LSG to pass through the grizzly and the screens may be washed into connecting launders, not shown.

13, are the box bearings in which are mounted the crank shaft 14, with ratchet and pawl 15, designed for adjusting to different angles the hinged grizzly 17, by means of the connecting wire ropes 16.

18, is a metal hopper, surmounting and supported on the wooden inclined frame and into which the material is first delivered for treatment.

19, are metal aprons fastened to the wood frame to receive ythe oversize from each screen and carry the same to connecting launders, not shown.

20, are heavy metal sheets, reinforced with the heavy angle bars 21, and held together by like cross angle bars, thus forming a rectilinear frame, which is vertically supported on springs 22, having also connecting rods 26, and auxiliary adjustable coil springs 23.

24, are pieces of steel riveted to cross angles 21, on which the involute wheels 36 coact.

25, are resilient cushions-preferably rubber, fastened on the cross bars 21, which are made to strike similar corresponding cushions fastened underneath timbers 4, these cushions producing a resilient action to the spring supported inner frame, when operated.

27 are openings cut in the sides of the frame, through which the shaft 35 passes.

28, are removable metal receptacles or pans carrying screen cloths of different mesh and adapted ,to be bolted to and made part of the said resilient inner frame represented by Fig. 2, with bolts 42. Said pans carry the spacing and supporting pipes or lianges 29 on which rest the screen cloths 31, with corresponding longer pipes or flanges 30 above the screen cloths, said cloths and pipes being fastened to said pans by bolts 32 and the projecting ends of the screen cloths being further secured to pipes 30 by the U bolts 33, as clearly shown in Fig. 3.

34, are angles riveted near the lower bottom edge of the pans for greater rigidity and strength.

85, is a shaft mounted in bearing boxes 38, attached tothe wood members 6, and which shaft carries the involute wheels 36 and pulleys 37.

39 and 40, are stationary inclined pans, provided with spacing pipes or flanges 43, forming channels, corresponding with the screen pan channels and adapted to conduct the material from the grizzly to the upper end of the topmost screen in said resilient frame, said material going into each kspace or channel between such pipes or flanges passes to a. corresponding space or channel in said screens, and so on throughout the series of screens, thus securing an even distribution of the material over each screen and pan. I preferably employ metal pipes for such spacing and securing of the screen cloths in the pans, as they are light and strong, the contact surface between such and the screen cloths is very little, and the rounded surface of the pipes presents no sharp corners to wear the screen cloths, but it will be understood that I do not limit my invention to the use of such, as other forms could be used.

In the embodiment illustrated a plurality of screen cariying inclined pans are shown disposed one above the other and bolted to the spring supported operable metal frame, thus permitting of their easy removal for repairs or change of screen cloths. These pans are fixed at a very considerable downwardly inclination, to give rapid travel to the material and in such manner that the material passing through each screen cloth is discharged directly from the lower edge of the shortened bottom of the pan onto the head or lhigh end of the screened pan next below, the channels formed in the pans by the flanges or pipes supporting and holding down the screen cloths, discharge into the corresponding channel of the next lower screen pan, and so on through the series thus preserving a uniform distribution of the material through the machine.

As will be observed, one of the novel and valuable features of this invention are the screen carrying receptacles or box like pans, wherein the bottom of the pan stops short of its sides and also the end of the screen cloth and upper pipes, thus producing an opening between the bottom of the pan and the head of the next contacting lower pan, and through which the material that passes through the screen goes directly to the head end of the screen next below, while the oversize is carried farther and passes out over the fixed aprons. Thus a direct, coperative, continuous connection between the plurality of screens is secured with a resultant oversize from each screen, and an undersize from the lowermost screen.

In the embodiment illustrated I show four screens, but it will be understood that I do not limit myself to a fixed number of such, as the character of the material to be treated or the number of sizes desired would control the number of screens used; but obviously the greater the number of screens used, the greater will be the tonnage capacity of such machine, provided the meshes or openings of the screen cloths be of such selection as that each screen will carry off about the same percentage of oversize; so, under this novel construction, a large number of screens can be used in the same frame, within a height practical for better results secured.

operation. As Will befseen, this operable screen carrying inner frame is mounted vertically preferably on carriage springs of suflicient strength to sustain the Weight and cause la moderate contact or impingement between the resilient cushions at the top, so with the auxiliary coiled springs the force of the down stroke of said frame can be most delicately governed, While the length of such stroke is regulated as between the contact faces of the involute Wheels and the plates fixed on said frame, against Which said Wheels contact or coact. "If the stroke be too'long, some of theI spacing packing between the shaft boxes and timber support may be removed, thus raising the shaft and involute Wheels. It will also be `observed that this spring supportedinner frame is in, practically perfectly balance, in operation, hence presents no lateral movement and but slight friction and Wear of the short retaining contact plates, near the tops of the inner and outer frames.

While I preferably employ ,the surmounted hopper and its connections, it is apparent that same could be dispensed with, Where Washing be not desired and the material may be delivered direct to the head of the uppermost screen.

As elsewhere stated, this "apparatus is adapted to handle material in either' a Wet or dry state or with yor Without Water, but I preferably employ Water as the travel and tonnage capacity is greatly increased and In the operation of this apparatus, which is especially Well adapted to the handling of placer mine material, such product, being sent to the hopper by various means, is usually made up of boulders and pieces of rock too largeI to pass through the grizzly, so the adjustably grizzly is set at the desired angle to hold thel material in the hopper, when a graduated Water spray is turned on, giving a graduated feed to the machine, and when the larger rock is Washed of its adhering material and ore, the grizzly is lowered t0 the same plane as the hopper bottom, when the Washed oversizes will pass by gravity into connecting launders and to the Waste dump, While the respective sizes from the screens go to devices calculated to save the contained values.

It is to be understood that I do not limit or confine myself to the details of construction herein shown and described, inasmuch as various minor changes, such as would suggest themselves to the skilled mechanic, may be made therein Without departing from the spirit or fundamental principles of my invention.
